124 | * <p>
|
||
125 | * A developer can register a set of <code>Behavior</code>, but only one (that
|
||
126 | * can be a composition of several) of them can be active. The active one
|
||
127 | * defines the way to work and access with its <code>MapContext</code>'s layers.
|
||
128 | * The active behavior, in combination with the appropriate {@link ToolListener
|
||
129 | * ToolListener} will allow user work with a particular <i>tool</i>.
|
||
130 | * </p>
|
||
131 | *
|
||
132 | * <p>
|
||
133 | * All mouse events produced on this component will be delegated to the current
|
||
134 | * active behavior, the <i>currentMapTool</i>.

143 | * information.

144 | * </p>
|

145 | *
|

146 | * <p>

148 | * </p>
|

149 | *

150 | * <p>
|

151 | * Paints the component according the following algorithm: <br>
|
||
152 | *   If <i>status</i> is <i>UPDATED</i>:<br>
|
||
153 | *     If there is a <i>double buffer</i>:<br>
|
||
154 | *       If there is a <i>behavior</i> for managing the
|
||
155 | * <code>MapControl</code> instance, delegates the drawing process to that
|
||
156 | * behavior, calling: <code><i>behavior_instance</i>.paintComponent(g)</code>.<br>
|
||
157 | *       Else, repaints the current graphical information quickly
|
||
158 | * calling: <code>g.drawImage(image,0,0,null)</code>.<br>
|
||
159 | *   Else, (<i>status</i> is <i>OUTDATED</i>, or <i>ONLY_GRAPHICS</i>):
|
||
160 | * executes a quickly repaint of the previous information calling
|
||
161 | * <code>g.drawImage(image,0,0,null)</code>, and creates a <i>painting
|
||
162 | * request</i> to delegate the heavy drawing process to the {@link Drawer2
|
||
163 | * Drawer2}'s worker thread, according the <i>SingleWorketThread</i> pattern,
|
||
164 | * starting a timer to update (invoking <code>repaint()</code>) the view every
|
||
165 | * delay of <code>1000 / drawFrameRate</code> ms. during that heavy drawing
|
||
166 | * process, and if its enabled <code>drawAnimationEnabled</code>. The
|
||
167 | * <i>painting request</i> once is being attended, invokes
|
||
168 | * <code>MapContext</code> to draw the layers:
|
||
169 | * <code>mapContext.draw(image, g, cancel,mapContext.getScaleView());</code>

173 | * <ul>
|
||
174 | * <li>The painting process can be cancelled calling {@link #cancelDrawing()
|
||
175 | * #cancelDrawing()}.</li>
|
||
176 | * <li>At last resort, the particular implementation of each layer in a
|
||
177 | * <code>MapControl</code>'s <code>MapContrext</code> will be that one which
|
||
178 | * will draw the graphical information, and, if supports, which could cancel its
|
||
179 | * drawing subprocess.</li>
|
||
180 | * <li>It's possible to force repaint all layers, calling
|
||
181 | * {@link #drawMap(boolean doClear) #drawMap(boolean)}.</li>
|
||
182 | * <li>It's possible repaint only the dirty layers, calling
|
||
183 | * {@link #rePaintDirtyLayers() #rePaintDirtyLayers()}.</li>
|
||
184 | * <li>It's possible repaint only the {@link GraphicLayer GraphicLayer}, calling
